BlueOptics Q28-AOC-1M-F5-BO InfiniBand Fibre Optic Cable 1m QSFP28 Male

The BlueOptics Q28-AOC-1M-F5-BO InfiniBand fibre optic cable is a 1-meter active optical cable with QSFP28 male connectors at both ends. Designed for short-reach, high-bandwidth interconnects, this cable supports high-speed data transmission required in data centers and high-performance computing clusters. Its compact form factor and QSFP28 interface provide compatibility with ports designed for 100Gb/s InfiniBand and related Ethernet environments, enabling direct-attached connections without the need for separate transceivers.

Advantages

This active optical cable offers low latency and high throughput over a 1 m length while reducing electromagnetic interference compared with copper alternatives. The QSFP28 male-to-male connectors simplify deployment in racks and switches that accept direct-attach QSFP28 modules. Its optical design lowers power consumption relative to some electrical solutions and provides stable signal integrity for demanding applications.

Suitable for

• Short-reach interconnects between switches, servers and storage in data centers
• High-performance computing clusters requiring InfiniBand connectivity
• Top-of-rack and leaf-spine network fabrics where QSFP28 ports are available
• Environments needing low-latency, high-bandwidth direct attached links

Key specifications

• Cable type: Active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 1 metre
• Interface: InfiniBand / compatible with QSFP28 100Gb-class ports
• Transmission medium: Multimode fibre optic (integrated transceivers)
• Typical applications: Short-reach high-speed data links

How to use

Ensure both devices have compatible QSFP28 ports and are powered down or set according to the host hot-plug guidelines. Align the QSFP28 connectors with the port openings and insert the cable until the latch engages. Verify link status via the host equipment management interface and allow the devices to negotiate link parameters. For removal, release the connector latch and pull the connector straight out to avoid stressing the cable or port.

Recommendations

Use this cable for planned short-distance links within racks or between adjacent racks. Avoid tight bends and protect the connectors from dust when not connected; follow equipment vendor guidelines for QSFP28 hot-plug handling and airflow management to maintain link reliability.
